We can't know everything, how and wherefore," said the old man. "It is ordained for the bird to have not four wings but two because it is able to fly with two; and so it is ordained for man not to know everything but only a half or a quarter. As much as he needs to know so as to live, so much he knows." ,From ''In The Ravine''~Chekhov~,
